Using Solr 5.3.1 in Solr Cloud mode deployed on AWS (each Solr instance has -Xmx 1024m and the server has 8GB of RAM)
Am getting a 500 error running a query via the UI Looking in the logs I just see this with no stack trace 2016-01-12 02:04:22.181 ERROR (qtp59559151-7313) [c:qa_us-east-1_here_account18 s:shard2 r:core_node4 x:qa_us-east-1_here_account18_shard2_replica2] o.a.s.s.SolrDispatchFilter null:java.lang.ArrayIndexOutOfBoundsException 2016-01-12 02:04:22.201 ERROR (qtp59559151-7267) [c:qa_us-east-1_here_account18 s:shard2 r:core_node4 x:qa_us-east-1_here_account18_shard2_replica2] o.a.s.c.SolrCore java.lang.ArrayIndexOutOfBoundsException I have examined the cluster state and there are no degraded shards. I am suspicious that an OutOfMemoryError earlier in the day is still occurring but I have not seen one recently solr_log_20160111_1510:java.lang.OutOfMemoryError: Java heap space When I inspect the service status it seems to say I am OK for memory [solr@qa-solr-us-east-1-4454eff7 logs]$ sudo service solr status Found 1 Solr nodes: Solr process 9641 running on port 8983 { "solr_home":"/solr/data/", "version":"5.3.1 1703449 - noble - 2015-09-17 01:48:15", "startTime":"2016-01-11T15:10:14.113Z", "uptime":"0 days, 11 hours, 22 minutes, 53 seconds", "memory":"665.3 MB (%67.8) of 981.4 MB", "cloud":{ "ZooKeeper":"ec2-54-173-143-61.compute-1.amazonaws.com:2181,ec2-52-90-213-206.compute-1.amazonaws.com:2181,ec2-52-90-108-64.compute-1.amazonaws.com:2181/solr", "liveNodes":"3", "collections":"56"}} Any thoughts or suggestions on how to debug further (ideally get the stack trace)?
